Answer:

This is the movement of molecules and ions from one medium to another,based on the concentration gradients, diffusion distant and area exposed. The plasma membrane is made up of phospholipid-bi-layer, to regulate what passes through.

However,because most of the molecules that diffuses across the membrane are small,non-polar, the bi -layer can not restrain their movements. O2, CO2 and lipids cross this barrier with ease by simple diffusion. However, polar molecules are restricted from passing through..

A zoologist analyzes the jawbones of an extinct mammal and concludes that it was an herbivore. The zoologist most likely came to this conclusion based on the shape of the teeth.

Animals that consume plants, such as deer, elephants, cows, and many others, are known as herbivores. They eat a range of vegetables, fruits, grasses, grains, and other foods depending on the habitat of the specific animal, hence they are essentially vegetarians.

The broad, flat teeth of herbivores are perfect for chopping up the plant material they consume. These animals' teeth enable them to break down the fibers in their food, making it much simpler for them to digest.

Plant-eating animals known as herbivores have large, flat molars and sharp incisors. They don't own any dogs. The incisors, canines, and molars of omnivores are used for a range of foods. The teeth of herbivores are designed to crush and ground vegetation.

Which species will most likely survive if earth temperature increase?
joja [24]

It's for sure not A because having thick fur will only make you hotter, and thus you will suffer a heat stroke. It's not C because small ears would not be long enough to provide you with cooling. That one does not make sense. It could be D, but the species would need to have alot of muscles in order to be consistently flapping there ears for the constant hear. Answer is B because it is the most logic, and the fewer amount of fur, the less hotter you will be, especially if your fur provides insulation.

Answer is B. Species B because fur would provide insulation.
